It's not a regional issue really, depending upon what you mean by internet TV. The BBC's iPlayer, C4's 4oD etc. are all available via web based services for UK people with a TV License. On the other hand if you mean IPTV then there aren't a lot of true IPTV solutions about right now, except for BT Vision. However new services like TalkTalk TV are due out soon. Again these are all UK products for UK people with good broadband connectivity. Internet TV comes over the internet and not your ariel.
